SLICING MACHINE.

Application filed February 28, 1921. Serial No. 448,398.

To all w homit may concern:

Be it known that I, HENDRIK STUKART, a citizen of the United States, residing at Laporte, in the county of Laporte and State of Indiana, have invented certain new and useful Improvements in Slicing Machines, of which the following is a specification.

This invention relates to machines for slicing meat and other material, and especially to the mechanism for feeding the material to the slicing knife and has for its object the provision of mechanism of the class named which shall be of improved construction and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims.

In the drawings Fig. 1 is an elevation of a portion of a slicing machine having one embodiment of the present invention applied thereto; and

Fig. 2 is a top plan view of the mechanism shown in Fig. 1.

In the slicing of some kinds of meat and also in certain species of fish it is desirable to cut the slices from the body of the material in a plane at an angle to the length of the piece. The present invention provides convenient means for holding such material so that it may be sliced at an angle on slicing machines of standard construction.

Referring more particularly to the drawings, the numeral designates the reciprocating table of the usual form of slicing machine mounted to slide on ways 11 and 12 which are supported from the base of the machine by uprights 13 and 1 1, respectively. Securely fixed to the top of the reciprocating table 10 is a plate 15 spaced upwardly a slight distance from the top ofthe table 10 and having a feed plate 16 slidably mounted adjacent the under face thereof. The feed plate 16 is held in position on the plate 15 by retaining strips 17 which overlap the edges of the plate 15. The plate 15 carries a pair of upwardly projecting bearing lugs 19 and 20 in which a feed screw 21 is journaled. A half nut 22 projects upwardly from the upper face of the plate 16 through a longitudinal slot in the plate 15 and engages the under side of the screw 21. It will be apparent that rotation of the screw 21 will feed the plate 16 along the top of the reciprocating table 10 and toward the slicing knife shown at 23. The screw 21 is rotated by ratchet mechanism 24: of standard construction which is periodically actuated by the reciprocation of the table 10in ama-nner well known in the art.

Pivotally mounted at 25 on the plate 15 adjacent the knife 23 is a tilting table 26 arranged to swing upwardly about the pivot 25 to various angular positions relative to the reciprocating table. Ratchet bars 27 are carried by the reciprocating table 10 and are provided with teeth 28 engaged by pawls 29 on the tilting table 26 for holding the tilting table in various angular positions.

Slidably mounted on the tilting table 26 is a meat plate 30 secured to side rails 31 mounted between guides on the tilting table 26. The guide at one side of the table may comprise a spring plate 32 held in place by screws 33 and having a laterally bent edge engaging a groove 34 in the rail 31. The plate 32 is resiliently pressed against the rail 31 by springs 35 carried by the screws 33 in order to hold the meat plate frictionally against lost motion on its inclined sup- )ort.

l Journaled between side rails 31 are a plurality of rods or bars 36 having meat-engaging tines 37 which may be projected outwardly through openings 38 in the plate 30 and into engagement with the material supported on top of the plate. The operation of the tines 37 is similar to that shown in Patent No. 1,356,165. The bars 36 are provided with intermeshing pinions 39 to provide simultaneous action on all of the tines 37 and one of the bars 36 is extended through the rail 31 and provided with a handle 40 by means of which the bars 36 may be actuated to move the tines 37 into and out of engagement with the material to be sliced. It will be seen that holding mechanism of this kind will secure the material upon the meat plate without the necessity of clamps or other holding apparatus arranged above the surface of the plate. If the usual holding clamp were used the upward inclination of the table would throw the top of the clamp forwardly toward the knife and thus prevent feeding of the plate into close proximity to the knife. Where the arrangement shown in the drawings is employed, however, it will be apparent that the holding mechanism for the material will in no way interfere with the movement of the plate toward the slicing knife so that the material may be sliced to a point close to the portion engaged by the holding mechanism;

The meat plate is fed forwardly toward the knife by a post or rod 41 projecting upwardly from a lug 42 on the feed plate 16. The rod 41 passes through an opening in a block 43 which is swiveled at 44 to the rail 81. of the meat plate 30. Forward movement of the feed plate 16 under the influence of the screw 21. will. be transmitted through the post 41 and the swivel block 43 to the meat plate so that the plate is fed toward the knife 23 after each slice has been cut preparatory to severing the next slice. The swivel connection betwen the block 43 and the rail 31 will permit movement of the meat plate 30 to its various angular positions without interfering with the operation of the feeding mechanism.

" I claim 1. In a slicing machine, a support for ma terial to be sliced, and. means for engaging the lower face of said material and for gripping said materi'al against said support.

- 2. The combination with a slicing machine, of a plate for supporting material to be sliced upon which said material rests, of means for engaging the face of said material adjacent said plate to hold said material in place on said plate said engaging means being arranged to penetrate the face of said material adjacent said plate at spaced points thereon and to grip said material against said plate.

3. The combination with a slicing machine having a concaved disc knife, of a work support upon which the material to be sliced is carried, and prongs distributed over the face of said support and arranged to engage the lower surface of the material and grip said material against said. support to enable said support to feed said material to said knife and to prevent said knife from drawing said material forwardly on said. support.

4. In a slicing machine, a slicing knife, a worksupport arranged at an angle to the cutting plane of said knife, and means for engaging the lower surface of material on said support to clamp said material to said support.

5. The combination with a slicing knife having an upright. cutting plane, of a work support arranged at an oblique angle to the horizontal, means for engaging the lower face of material. on said support and for clamping said'material against said support, and means for feeding the material thus clamped toward said slicing knife.

6. The combination with a slicing knife, of a plate for supporting material to be sliced and upon which said material rests, and means distributed over the face of said plate for engaging the surface of said material. contacting therewith, said means being arranged to clamp said material to said plate at positions distributed over the face thereof.

7. The combination with a slicing knife having an upright cutting plane, of a guideway pivotally supported adjacent said knife to swing into various positions of adjustments at an oblique angle to the horizontal, a work supporting plate slidably mounted on said guideway, holding means distributed over the face of said plate and arranged to enter the surface of material thereon a to clamp said material to said plate, andmechanism for feeding said plate along said guidewaytoward said slicing knife.

8. The combination with a slicing knife having a beveled edge operating in an up right cutting plane, of a guideway pivotally supported adjacent said knife to swing into various positions of adjustment at an oblique angle to the horizontal, a work-supporting plate slid'ably mounted on said guideway, holding means distributed over the face of said plate and arranged to enter the surface of material thereon to clamp said material to said plate, and mechanism for feeding said plate along said guideway toward said knife, said holding means being operative to retain said material against movement toward said slicing kni-fe during the slicing operation of saidknife.

In testimony whereof I have signed my name to this specification on this 25th day of February A. D. 1921.
